DETAILED DESCRIPTION

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

FIG. 1 illustrates, in a block diagram, a computing environment in accordance with certain embodiments. A first device 100 is coupled to a second device 150. Although two devices are shown, any number of devices may be used in embodiments of the invention. The A first device 100 includes a zoom engine 120, content 130, and a first display screen 140. The second device 150 includes a zoom engine 170, content 180, and a second display screen 190. Zoom engine 120 and zoom engine 170 communicate and work together to allow a portion of content 130 to be shown as zoomed (via a zoom operation) on the second display screen 190. In various embodiments, the content 180 may be a copy of the content 130 or may be a subset of the content 130.

With embodiments, when content 130 is displayed on the first display screen 140 and is selected for zooming in the first device 100, the content 130 remains unchanged in the first device 100, but the zoom engine 120 communicates with the zoom engine 170 to have the zoomed content displayed on the second display screen 190. Then, a user is able to see the entire content 130 on the first display screen 140, while seeing a zoomed portion of the content on the second display screen 190.

By having the partial content to be zoomed transferred to the second device 150 and displayed on the second display screen 190, the zoom engine 120, 170 avoid having the zoomed content blocking viewing of the original content.

With the zoom engine 120 on the first device 100, a user may select any content (e.g., a text portion, an image portion, a map portion, etc.) to be zoomed, and the zoom engine 120 communicates this request to the zoom engine 170, which displays the zoomed content on the second display screen 190 for viewing by the user.

Because the first device 100 shows the entire content, the user can view the other associated content on the first display screen 140.

In certain embodiments, the user may view the “street view” in the first display screen 140 on the first device 100 and the associated map is displayed on the second display screen 190 on the second device 150. A street view may be described as a set of street-level images (e.g., photographs of a street taken from street-level to show buildings, parks, etc. on that street).

FIG. 2 illustrates an example of zooming on content using two devices in accordance with certain embodiments. In FIG. 2, the first display screen 140 on the first device 100 displays an image 210 adjacent to text 220. Although not shown in FIG. 2, the first device 100 also includes the zoom engine 120 and the content 130, while the second device 150 includes the zoom engine 170 and the content 180. In FIG. 2, a user has selected (e.g., by using a device, such as a mouse or finger) the image 210 for zooming. In response to the user requesting to zoom in on the image 210, the zoom engine 120 communicates the request to the zoom engine 170, and the zoom engine 170 displays the zoomed image 210 on the second display screen 190 on the second device 150.

FIG. 3 illustrates another example of zooming on content using two devices in accordance with certain embodiments. In FIG. 3, the first display screen 140 on the first device 100 displays a map 310. Although not shown in FIG. 3, the first device 100 also includes the zoom engine 120 and the content 130, while the second device 150 includes the zoom engine 170 and the content 180. In FIG. 3, a user has selected (e.g., by using a device, such as a mouse or finger) a portion 320 to be zoomed in. In response to the user's selection of the portion 320 of the map, the zoom engine 120 communicates the request to the zoom engine 170, and the zoom engine 170 displays the zoomed portion 320 of the map on the second display screen 190 on the second device 150.

Thus, the zoomed content displayed on the second display screen 190 does not provide a distraction for the user and does not obstruct any of the original content on the first display screen 140.

FIGS. 4A and 4B illustrate, in a flow diagram, operations for zooming in on a portion of content in accordance with certain embodiments. Control begins at block 400 with the zoom engines at each of multiple devices creating a pairing between the multiple devices to enable them to communicate with each other. Each of the computing devices has a display screen for display content or a portion of content. In certain embodiments, a user uses the zoom engines to create the pairing. In certain embodiments, the zoom engines at the multiple devices communicate with each other via a local area wireless technology (“WiFi”) or via Bluetooth wireless technology.

In block 402, the zoom engines receive designation of one of the computing devices as a first device, and then the remaining computing devices are designated as second devices. A user may change this designation so that a different computing device becomes the first device.

In block 404, the zoom engine on the first device obtains screen dimensions of each second display screen on each second device. In block 406, the zoom engine on the first device displays content on a first display screen. In block 408, the zoom engine on the first device receives selection of a portion of the content displayed on the first display screen for zooming. From block 408, processing continues to block 410 (FIG. 4B).

With reference to the processing of block 408, if text is selected, then the zoom engine on the first device gathers the font size of the selected text; and, if an image or map section is selected, then the zoom engine on the first device identifies an area dimension. This information is used to apply the zoom operation to the selected portion. In certain embodiments, the first device collect this information and sends the information to the second device. The second device uses the information to perform the zoom operation.

In block 412, the zoom engine on the first device receives selection of a second device. In certain embodiments, one of the multiple devices may be set as a default, second device, and this operation is skipped. In block 414, the zoom engine on the first device receives selection of a zoom level.

In block 410, the zoom engine on the first device determines whether the portion can be zoomed on the second device. If so, processing continues to block 416, otherwise, processing continues to block 420. For example, the zoom engine on the first device may determine that the screen dimensions on the second device will not accommodate zooming the portion at the zoom level, and processing will go from block 410 to block 420.

In block 416, the zoom engine on the first device sends the portion and the zoom level to the zoom engine on the second device. In certain embodiments, the zoom engine on the first device performs the zoom operation and sends the zoomed portion to the zoom engine on the second device. In certain embodiments, the zoom engine on the second device receives the portion and the zoom level and performs the zoom operation. In block 418, the zoom engine on the second device displays the portion at the zoom level on the second display screen.

In block 420, the zoom engine on the first device notifies a user that the selected portion cannot be zoomed.

In certain embodiments, the first device may be a mobile computing device (e.g., a smart phone, a laptop computer, etc.), a non-mobile computing device (e.g., a desktop computer, etc.), a television, etc. In certain embodiments, the second device may be a mobile computing device (e.g., a smart phone, a laptop computer, etc.), a non-mobile computing device (e.g., a desktop computer, etc.), a television, etc. This allows the user to make use of larger screen sizes for viewing the zoomed content. Embodiments provide the ability to zoom in (using an external screen) on a portion of content, without hampering the use of the initiating, first device (which may have a relatively small display screen), which is not consumed by the zoomed image.

FIG. 5 illustrates a computer architecture 500 that may be used in accordance with certain embodiments. In certain embodiments, computing devices 100 and/or 150 may implement computer architecture 500. The computer architecture 500 is suitable for storing and/or executing program code and includes at least one processor 502 coupled directly or indirectly to memory elements 504 through a system bus 520. The memory elements 504 may include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution. The memory elements 504 include an operating system 505 and one or more computer programs 506.

Input/Output (I/O) devices 512, 514 (including but not limited to keyboards, displays, pointing devices, etc.) may be coupled to the system either directly or through intervening I/O controllers 510.

Network adapters 508 may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters 508.

The computer architecture 500 may be coupled to storage 516 (e.g., any type of storage device; a non-volatile storage area, such as magnetic disk drives, optical disk drives, a tape drive, etc.). The storage 516 may comprise an internal storage device or an attached or network accessible storage. Computer programs 506 in storage 516 may be loaded into the memory elements 504 and executed by a processor 502 in a manner known in the art.

The computer architecture 500 may include fewer components than illustrated, additional components not illustrated herein, or some combination of the components illustrated and additional components. The computer architecture 500 may comprise any computing device known in the art, such as a mainframe, server, personal computer, workstation, laptop, handheld computer, telephony device, network appliance, virtualization device, storage controller, etc.
